Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519022, here are decompositions:

61 + 31518961 = 31519022
109 + 31518913 = 31519022
163 + 31518859 = 31519022
229 + 31518793 = 31519022
331 + 31518691 = 31519022
349 + 31518673 = 31519022
421 + 31518601 = 31519022
433 + 31518589 = 31519022

Showing the first eight; more decompositions exist.
